Put in the wrong place and lose? (6)
I believe the answer is:
mislay
I believe this clue is a double definition.
'put in the wrong place' is the first definition.
(I've seen this in another clue)
'lose?' is the second definition.
('mislay' can be a synonym of 'lose')
'and' acts as a link.
(Other definitions for mislay that I've seen before include "Set in wrong location" , "Put something aside and forget where" , "Be unable to find" , "Put in wrong place, lose temporarily" , "Lose track of" .)
